A Numeric Sender ID is a phone number used as the sender identity when sending SMS messages, instead of a text-based or alphanumeric name. It appears as a standard mobile number on the recipient’s device and is commonly used for transactional messages where replies may be expected.
Key Points:
-Identification: Shows a real phone number as the sender.
-Message Type: Mostly used for transactional SMS like OTPs, alerts, or service notifications.
-Reply Enabled: Recipients can usually reply directly to the numeric sender ID.
-Reliability: Ensures higher delivery rates since mobile carriers recognize it as a valid number.
Difference from Alphanumeric Sender ID:
-Numeric Sender ID: Uses a phone number; can receive replies.
-Alphanumeric Sender ID: Uses a name or brand (e.g., “BANKXYZ”); usually one-way messages, replies are not supported.
Example:
If a bank sends an OTP from the number +91 9876543210, this number is the numeric sender ID, and the user can reply if needed.
